We call it cowpeas, it is like green bean but with greater taste.

It can be consumed with the back-shell when green and tender, but when fully browned, the back gets stronger and then the seed inside becomes the only one eatable which can be prepared like bean.

Maybe there’s something better that it’s known for; something like it’s botanical name may help you. But then, you may wish to google it for better understanding.

I don’t mind sending some across to America if that can help my friend 😄😄

Remain awesome beloved Elizabeth.
